Although it's not a lightweight at 7+ lb., I'm very happy with my HP ze4315us notebook I bought about 6 weeks ago. AMD 1800+, 15" screen, and DVD/CD-RW, 256MB, 30GB HDD, it's a great portable. Shows off my Bahamas trip pics great too.
At $999 with a $250 rebate from Best Buy it only cost me $750, with 0% interest rate over 6 months. Delivery was free and arrived in 3 days. That is hard to beat!
